Abstract

A system for anchoring a catheter to the body of an individual is disclosed, which includes a device-grasping means and an anchoring means. The device-grasping means includes a housing in which a catheter or other medical device can be securely and rapidly attached or detached from the anchoring means. The anchoring means includes one or more arcuate needles attached to each other by means of a shaft. The arcuate needles are rotatably supported on the housing, and are locked into position when in the engaged and unengaged positions. The anchoring means further includes portions in which the sharpened tips of the arcuate needles reside when in the engaged and unengaged positions in order to prevent injury to medical or other personnel.

7. The apparatus of

claim 1

, wherein said device-grasping means further comprises:

(a) a housing, said housing having a first bore extending therethrough, and;

(b) at least one plug, said at least one plug formed from an elastic material and having a second bore that extends therethrough, said at least one plug shaped to securely fit into either end of said first bore in said housing.

8. The apparatus of

claim 7

, wherein a slit extends from an outer circumference of said at least one plug to said second bore.

9. The apparatus of

claim 7

, wherein said housing further comprises a first lip and a second lip, said first lip capable of securing said anchoring means in a first unengaged position, and said second lip capable of securing said anchoring means in a second engaged position.

10. The apparatus of

claim 7

, wherein a groove is formed in a portion of said housing that comes into contact with said patient'"'"'s tissue.

11. The apparatus of

claim 7

, wherein

(a) said at least one plug includes a ridge that extends around an outer circumference thereof, and

(b) said housing includes a groove that extends around an inner circumference of said first bore, whereby said ridge will engage said groove at a point at which said at least one plug is properly engaged with said housing.

12. The apparatus of

claim 7

, wherein said at least one plug includes a flange that extends around an outer circumference of a first end thereof.

13. The apparatus of

claim 7

, wherein said at least one plug is attached to said housing by means of a hinge.

14. The apparatus of

claim 7

, wherein said second bore extending through said at least one plug includes a first opening and a second opening, said first opening smaller than said second opening, and said at least one plug further includes a diaphragm formed of an elastic material that extends around an inner circumference of said first opening.

15. The apparatus of

claim 1

, wherein said device-grasping means is tubular in shape and is formed from a resilient material, and further includes a slit that is formed in and extends along the length of said device-grasping means.

16. The apparatus of

claim 15

, wherein at least one tab is disposed on said device-grasping means on each side of said slit, whereby said tabs can be used to deform said device-grasping means such that a diameter thereof is temporarily increased.

17. The apparatus of

claim 1

, wherein said device comprises at least one catheter.

18. The apparatus of

claim 17

, wherein said device-grasping means holds said at least one catheter in a position generally parallel to said patient'"'"'s tissue.

19. The apparatus of

claim 1

, wherein said device-grasping means comprises an inner core formed from an elastic material, said inner core generally tubular in shape and having an outer circumference that is eccentric in cross-section, a second bore that extends therethrough, and a slit that connects said outer circumference to said second bore.

20. The apparatus of

claim 19

, wherein a cross section of said inner core is elliptical.

21. The apparatus of

claim 19

, further comprising:

(a) a housing, said housing having a first bore that extends therethrough and a slit that connects said first bore to an outer circumference of said housing, said first bore having a cross section that is similar in shape but proportionally larger than said eccentric cross section of said inner core, and a groove that extends around an inner circumference thereof; and

(b) a first end of said inner core includes a lever attached thereto, and a second end of said inner core includes a ridge that extends around said outer circumference;

wherein said inner core can be secured in said housing by engaging said ridge and said groove, and rotating said inner core by means of said lever.

22. The apparatus of

claim 1

, wherein said at least two anchors are disposed parallel to each other, and said at least two anchors further include:

(a) at least two members, each of said at least two members extending from each second end of said at least two anchors toward a center of a circle defined by each of said at least two anchors, and;

(b) a shaft, said shaft connected to and extending between said at least two members.

23. The apparatus of

claim 22

, wherein said anchoring means further comprises an anchor handle attached to said at least two anchors, and said anchoring means is rotatably fixed to said device-grasping means and rotates between a first unengaged position and a second engaged position around a central axis defined by said shaft.

24. The apparatus of

claim 22

, wherein said device-grasping means further comprises a first jaw and a second jaw, wherein said device is held in place between said first jaw and said second jaw.

25. The apparatus of

claim 24
